Today, thousands of students are taking to the streets to protest gun violence, imploring officials to do something, anything, after the tragedy in Parkland, Florida, last month. Starting at 10 a.m. this morning, students and others disenchanted by the unwillingness of U.S. lawmakers to enact sensible gun legislation left their classrooms and workplaces en masse, and made their presence known.

The walkouts took place at schools across the country. Here’s a few pictures and videos of the protests:
